Gardening in wetter areas

The following wildflowers will do well in areas that are consistently moist or regularly very wet. These plants have a high water requirement and can outcompete other plants when plenty of water is available. These plants are therefore found in areas where the soil surface is close to the water table. This occurs in riparian environments, flood plains and in wet meadows where sub-surface drainage may be slow. Do not presume that these plants can survive well in clay soils in which water movement can also be quite slow.

Here is a list of perennials and shrubs that will survive well in a wet environment. True aquatic species are not included in this list.
